Hi,
I am working on a big scene, lots of rooms and floors. Fore some reason I need to be able to make a whole floor become semi-transparent… Of course i have display order issues.
I was given the advise to use order independant transparency or Depth Peeling.
I dont have any idear how to use that 
(I m quite new with unity)
Any tutorial, Shaders, … that can help me ?
Thanks
you just need a glass like floor

check out the shader script there and manipulate the variables to get your desired effect
I’m gonna test that thanks !
